I know for a fact we do not have Office 365, yet it seems that our domain/tenant name is already taken. I'm the IT Manager for my organisation. I've been researching and it is possible that the tenant name was taken when/if someone signed up for a trial of Teams or Power Bi(?) or perhaps other microsoft services(?). It may also be due to the fact that a while ago I signed up for the free/community powerapps account to test its capabilities but I never used it.
What I would like to know is how can I sign up for a Teams free account as the admin and be able to create teams, etc. Is there a way to delete the current tenant name in use by the trials or powerapps free account? I don't mind getting rid of all the trials and powerapps accounts. Does anyone know who or where can I contact someone to get this fixed? I would really like to setup Teams as I strongly believe this will be a gateway to the Office 365 ecosystem. Thank you.
